PHILIP SHERIDAN \VILLIS, OF TOLEDO, OHIO.

GRAIN-SEPARATOR.

SPECIFICATION forming part of Letters Patent No. 393,411, dated November 27, I888.

Application filed February 23, 1888. Serial No. 265,066.

To aZZ whom it may concern.-

Be it known that I PHILIP SHERIDAN WIL- Lis, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Grain Separators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in machines for separating grain, more especially adapted to the cleaning of beans, seeds, coffee, and other like grains, and in separating them from foreign snbstancessuch as stones and other grains and seeds of varying densities-which in commercial condition are often found commingled as a mechanical mixture.

It further relates to the coolingof coffee immediately succeeding the roasting process, which,for well-known reasons, must be quickly performed, and to the cooling and drying of grains which from any cause have become heated or wettcd and require manipulating to divest them of contained heat or moisture.

I attain these objects by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a side elevation of my improved machine. Fig. 2.is a vertical section on line B. Fig. 1.

per 0 and the case D is located a gate, F,

which is adapted to entirely close or'partly or wholly open the passageway between the parts 0 and D. The conveycrD is connected to a power-shaft, and may be rotated any desired velocity by means of the pulley F in the ordinary manner of operating such conveycrs. The case E, extending upward a suffi- (No model.)

cient distance, which is fixed by the altitude at which it is desired to deliver the grain after it has been operated upon, terminates in a curved top, from which extends downward,at an angle preferably of about thirty degrees from the ascending limb of the said case E, and in a direction continuing the curve of said top, an arm,which in the illustration given is divided into two parts, G and G, and pivoted at H within said arm is a swinging partition, H, which is adapted to be moved to the right or left to the posit-ion represented by dotted lines K K. Connecting with the case E by means of the pipe I is a suction or exhaust fan, J, of ordinary well-known construction.

L is an ordinary blastfan, which connects through the spout M with the case E. The

spout M is made to swing on a horizontal pivot.M, passing laterally through said spout, at the point where the latter passes loosely through the wall of the case E, for the purpose of adjusting the direction of the blast from the fan L.

At N is located a receptacle, which in the illustration given is constructed in the form ofa drawer, and having above it at O a gate which is adapted to open and close the connecting passage-way between the case E and the said drawer N.

At P, across the top of the case E, is an opening, which is covered with a screen, over which slides a gate, P, for tightly closing more or less of said opening, as may be desired, to regulate the machine, all as hereinafter described.

The operation of this device is as follows: The material to be c1eanedsuch as ordinary coffee of commerceis placed within the hopper 0, or conducted thereto by means ofany well-known mechanism for conveying such material, when, by means of the conveyor D, (which, as beforedescribed, is driven by means ofthe power-pnlleyF,) the said coffee is slowly delivered at a uniform rate, falling in a scattering stream within the case E, as shown at @111 Fig. 2,where it meets a blast of air coming from the fan L through the spout M. By this means the said coffee is forced'upward through theease E in the direction of the arrow B, while heavier substances-such as stoncs,nails, &c.fall by the force of gravity into the drawer N. Continuing on its course, the asascending volume Q is carried over beyond the partition II and precipitated down the arm G, a part of the lighter dust passing out through the screen at P, and a part of the said lighter dust and such substances asleaves and strings and like material passing out by suction or by exhaustion through the exhauster J. 3

It is obvious that by a proper adjustment of the gate 1*, the spout M, the partition H, and gate P, in connection with a properly-speedcd t'an, L, and oxhauster J, these separations may be controlled at will.

It is also obvious that for some simple separations the arm G and exhauster J would not be required.

Having described my invention, what I claim as new, and desire to secure by Letters latent, is-

1. In a graitrseparator, a vertical case, E,

having a curved top and a downwardly-inclined discharge-arm continuing the curve of said top, the curved top being provided with an opening, P, a screen covering said opening, a gate, P, for adjusting the size of said opening, an adjustable partition, 11, within said discharge arm, a blast-fan, L, near the lower end of said case, a feed hopper, 0, opening into said case above the mouth of said blastfan, and a discharge-pipe, I, loading from said curved top at a point beyond said opening I and above the line of the upper end of said partition, substantially as and for the purpose set forth.

2. The blasttan L, hopper O, and case 15, in combination with the funnel-shaped spout M, passing loosely through the body of said case and pivoted therein at its point of passage, the larger cnd of said spout swinging over the mouth of said fan and the smaller end standing below the mouth of said hopper, substantially as and for the purpose set forth.

In testimony whereof I have affixed my sig- 1 nature in presence of two witnesses.
